Application November 22, 1938, Serial No. 241,822

4 Claims. (Cl. :iE 25) (Granted under the act of March 3, 1883, asamended April 30, 1928; 370 0. G. 757) The invention described hereinmay be manufactured and used by or for the Government for governmentalpurposes, without the payment to me of any royalty thereon.

The subject of this invention is an extractor for firearms and theinvention relates more especially to an extractor which is well housedin the bolt thereby rendering the structure more compact and less liableto injury, which contains no attenuated spring members as a part of theextractor proper, and which is so constructed and situated as to limitthe play of the firing pin and ejector.

To these and other ends, the invention consists in the construction,arrangement and combination of elements described hereinafter andpointed out in the claims forming a part of this specification.

In the accompanying drawing in which a preferred embodiment of theinvention is shown by way of illustration:

Fig. 1 is a view in front elevation of a bolt with an extractorconstructed in accordance with the invention in place therein;

Fig. 2 is an enlarged fragmentary plan view of the bolt partly insection to show the situation of the extractor;

Figs. 3, 4, 5 and 6 are detail views of the extractor.

The bolt I is bored axially to receive the firing pin 2 and also boredlongitudinally to receive the ejector 3.

A transverse bore 4 is formed in the bolt communicating with the axialbore and longitudinal bore and is adapted to receive the trunnion orpivot arm 5 of the extractor, which arm extends through grooves B and Iin the firing pin and ejector respectively, thereby limiting themovement of the firing pin and ejector and holding these elementsagainst rotation.

At its upper end the bore 4 communicates with an angularly disposed slot8 in the peripheral bolt adapted to receive the arm 9 of the extractorwith a fit sufiiciently free to allow the curved lip ll) of theextractor head I l to snap by and engage in front of the head of acartridge.

A resilient element herein shown as a coiled spring [2, is housed in arecess in the bolt and urges a hemispherical member l3 into contact witha depression M in the head of the extractor thereby urging the extractortoward cartridge engaging position.

I claim:

1. A bolt mechanism for a gun including a bolt having a firing pinreciprocable therein, said firing pin provided with a groove, an ejectormounted in said bolt and formed with a groove, an extractor mounted insaid bolt embodying a trunnion extending through the grooves to limitthe movement of the firing pin and ejector, an arm extending laterallyfrom the trunnion nested in the bolt, a head formed on the arm andprovided with a depression, a resiliently actuated member seated in thedepression to urge the extractor toward cartridge engaging position, anda cartridge engaging lip formed on the head.

2. The combination with a bolt having a firing pin and an ejectorreciprocable therein, said pin and ejector each provided with a groove,of an extractor embodying, a trunnion journaled in the bolt andextending through the grooves to limit the movement of he pin andejector, an arm extending laterally from the trunnion and nested in thebolt, a head on the arm, a cartridge engaging lip formed on the head,and means for forcing the lip into engagement with a cartridge.

3. A bolt mechanism for a gun including-a bolt, a reciprocable firingpin axially in the bolt and having a groove, a reciprocable cartridgeejector in the bolt parallel to the firing pin and having a groove, andan extractor having a trunnion journaled in the bolt and disposed in thegrooves of the firing pin and ejector to limit their reciprocablemovement and hold them against rota.-

tion.

4. A bolt mechanism for a gun including a bolt having an axial firingpin bore and a transverse bore intersecting the axial bore, said boltalso having ,a peripheral slot extending angularly from the transversebore to the front end of the bolt, an extractor having a trunnionjoumaled in the transverse bore, an arm integral with the trunnion andnested in the slot, and an arcuate cartridge engaging head integral withthe arm.
